This application is a continuation of International Patent ApplicationNo. PCT/CN2018/079402 with a filing date of Mar. 19, 2018, designatingthe United States, now pending, and further claims priority to ChinesePatent Application No. 201810038215.0 with a filing date of Jan. 16,2018. The content of the aforementioned applications, including anyintervening amendments thereto, are incorporated herein by reference.

TECHNICAL FIELD

The present application relates to a mangling device for fibers, fiberwebs or analogues, which belongs to the technical field of liquidremoval of textile materials.

BACKGROUND OF THE PRESENT INVENTION

Water squeezing as a critical procedure in a dyeing process is used tosqueeze and dehydrate washed fibers or fiber webs and other analogues.The existing mangling machine mainly includes a pair of upper secondrollers, a group of upper and lower conveyor belts and a plurality ofupper and lower driving rollers. Referring to FIG. 1, an upper conveyorbelt 3 a is sleeved among upper driving rollers 5 a; a lower conveyorbelt 4 a is sleeved among lower driving rollers 6 a; an upper roller 1 aand a second roller 2 a are located in loops of the upper conveyor belt3 a and the lower conveyor belt 4 a respectively; and a certain spacefor a fiber layer 7 a to pass is reserved therebetween. When the upperand the lower conveyor belts move simultaneously, the fiber layer 7 a isclamped by the upper and the lower conveyor belts to move forward. Themangling machine of this structure is convenient to use and high inprocessing capacity. However, since the fiber is squeezed by contactpoints of the upper second rollers; the pressure is mainly concentratedon the middle contact point, while two sides of the upper and the lowerrollers are both in a loose state, so that a majority of water squeezedout from the fiber layer 7 a may fall onto the lower conveyor belt 4 aand is discharged from meshes on the lower conveyor belt 4 a, but thereis still some water. Since the fiber layer 7 a is loosened withoutcompression after passing through the upper second rollers, theremaining water may be absorbed into the fiber layer 7 a again.Therefore, the actual dehydration rate is not high, which affects theoverall dehydration effect of the fibers, the fiber layer and theanalogues.

Based on this, the present application is proposed.

SUMMARY OF PRESENT INVENTION

For the above defects of the existing mangling process, the presentapplication provides a mangling device for fibers, fiber webs oranalogues, which can realize efficient dehydration and reduce the backabsorption of the dehydrated water.

To realize the above purpose, the present application adopts thefollowing technical solutions:

A mangling device for fibers, fiber webs or analogues comprises tworollers and two conveying mechanisms, and at least one of the tworollers is a driving roller. The conveying mechanism comprises at leastone driving roller, a plurality of carrier rollers and guiding beltsinstalled on the driving roller and the carrier rollers in a tensioningmanner. A space which is used for the fibers, the fiber webs or theanalogues to pass is arranged between the two guiding belts, and theportions of the two guiding belts forming the passing space of thefibers, the fiber webs or the analogues are parallel to each other. Thetwo rollers are respectively installed on positions corresponding to thepassing space of the two guiding belts.

Further, preferably:

At least one of the guiding belts of the two conveying mechanisms isprovided with a drain passage, and preferably, the drain passage isformed by leakage holes, a water conveying channel or a moistureabsorption belt. When the leakage holes, the water conveying channel,the moisture absorption belt or meshes and other structures are arrangedon the guiding belt as the drain passage, the overflow of liquid such aswater from the squeezed fibers or fiber webs can be facilitated, so thatthe separation efficiency of the liquid such as the water from thefibers or the fiber webs can be improved; or the guiding belt is set asa felt structure, a felt-like structure, a Teflon mesh or a steel wiremesh, and compared with the drain passage, the guiding belt of the feltor felt-like structure can improve the mangling effect under anextremely small force.

At least one of the two rollers is connected with a pressurizingmechanism to increase the pressure between the two rollers. Preferably,the pressurizing mechanism adopts an air cylinder (for example, the aircylinder is cooperated with a big arm, the big arm is installed betweenthe air cylinder and the corresponding roller, and the air cylinderdrives the big arm to rise and fall to drive the corresponding roller tomove up and down, so that a space between the rollers is changed, thatis, the pressure applied to the fibers, the fiber webs or the analoguesbetween the two rollers is changed), an electromagnetic way, amechanical way or a similar way to lift the corresponding rollers so asto change the pressure between the two rollers.

A water tank is arranged below the guiding belt and used to receive thewater squeezed from the fibers or the fiber webs. More preferably, thewater tank is located in the loop of the guiding belt. With the watertank, the environmental pollution caused by the splash of the squeezedwater and the secondary pollution of the fibers, the fiber webs or theanalogues can be avoided. When the water tank is arranged in the loop ofthe guiding belt, it is considered that the guiding belt may move fromthe original squeezed position to below the original squeezed positionalong with the rotation of the corresponding driving rollers, thesqueezed and falling liquid such as the water drops onto the guidingbelt and may be carried to the squeezed position again. In order toavoid the secondary dehydration caused by the carrying, the water tankis arranged in the loop of the guiding belt to prevent the water fromdropping onto the guiding belt below the squeezed position, therebyimproving the dehydration rate in the entire operation process.

The two rollers are arranged corresponding to each other in the verticaldirection or arranged in a staggering manner. The rollers are main partsfor squeezing the fibers, the fiber webs or the analogues between theguiding belts. When the two rollers are arranged corresponding to eachother in the vertical direction, and when the fibers, the fiber webs orthe analogues pass through the two rollers, the upper surface and thelower surface thereof are squeezed by the two rollers respectively, andthe liquid such as the water is rapidly separated out from the uppersurface and the lower surface. When the two rollers are arranged in astaggering manner, the fibers, the fiber webs or the analogues passthrough one roller first to be primarily squeezed between the roller andthe corresponding guiding belt, the liquid such as the water is squeezedout from the fibers, the fiber webs or the analogues, and then thefibers, the fiber webs or the analogues continuously pass through thesecond roller to be secondarily squeezed between the second roller andthe guiding belt corresponding thereto, and the liquid such as the wateris squeezed out from the fibers, the fiber webs or the analogues. Inthis way, by virtue of one-time or multi-time squeezing, the liquid suchas the water can be gradually separated out from the fibers, the fiberwebs or the analogues.

A tensioning wheel is installed in the loop of the guiding belt. Thetensioning wheel is preferably installed on an axis perpendicular to theguiding belt and moves up and down along the axis so as to adjust thetension of the loop of the corresponding guiding belt.

A rectifying wheel is arranged in the loop of the guiding belt. Therectifying wheel is preferably arranged in a front section of the loop.In a transfer process of the fibers, the fiber webs or the analogues,along with the rotation of each roller shaft, the deviation phenomenonis likely to occur. In order to avoid the transfer mistake, therectifying wheel is arranged in the loop of the guiding belt. Therectifying wheel is preferably arranged in the front section of theloop. The rectifying wheel is arranged near the front, so that thesubsequent transfer accuracy is guaranteed.

The driving rollers in the two conveying mechanisms are respectivelycalled the first driving roller and the second driving roller. Therollers are respectively called the first roller and the second roller.The first driving roller, the first roller, the second driving rollerand the second roller are arranged according to the following way:

A pair of first driving rollers is arranged. An outer diameter of thefirst driving rollers is greater than that of the first roller. Theguiding belt corresponding to the first driving roller is sleeved on thefirst driving roller. The first roller is located at the loop of oneside of the guiding belt close to other guiding belt. More preferably,at least one first roller is provided. The outer diameter of the firstdriving roller is greater than that of the first roller. One pair offirst driving rollers can satisfy the distribution of the first rollerin the loop of the guiding belt thereof. This structure is convenient tooperate, few in components and more stable to control.

A pair of second driving rollers is arranged. An outer diameter of thesecond driving rollers is greater than that of the second roller. Theguiding belt corresponding to the second driving rollers is sleeved onthe second driving rollers. The second roller is located at the loop ofone side of the guiding belt close to other guiding belt. Morepreferably, at least one second roller is provided. The outer diameterof the second driving rollers is greater than that of the second roller.One pair of second driving rollers can satisfy the distribution of thesecond roller in the loop of the guiding belt thereof. This structure isconvenient to operate, few in components and more stable to control.

A plurality of first driving rollers (≥3) are provided. The guiding beltcorresponding to the first driving rollers is sleeved on a closed pathformed by the plurality of first driving rollers. The first roller islocated at the loop of one side of the guiding belt close to the otherguiding belt. More preferably, at least one first roller is provided.The plurality of first driving rollers can form a structure with a largespace in the guiding belt. When the first rollers are distributed in theloop of the guiding belt, there is no need to consider the sizerequirements of the first driving rollers and the first roller, so thatthe operation is more flexible, the replaceability and the universalityare better, and the control is more stable.

A plurality of second driving rollers (≥3) are provided. The guidingbelt corresponding to the second driving rollers is sleeved on a closedpath formed by the plurality of second driving rollers. The secondroller is located at the loop of one side of the guiding belt close tothe other guiding belt. More preferably, at least one second roller isprovided. The plurality of second driving rollers can form a structurewith a large space in the guiding belt. When the second rollers aredistributed in the loop of the guiding belt, there is no need toconsider the size requirement of the second driving rollers and thesecond roller, so that the operation is more flexible, thereplaceability and the universality are better, and the control is morestable.

The present application is applied to the separation of the liquid suchas water from the fibers, the fiber webs or the analogues; the twoguiding belts are driven by the driving rollers to rotate; the fibers,the fiber webs or the analogues are clamped by the two guiding belts tomove forwards under the relative motion of the two guiding belts; andwhen the fibers, the fiber webs or the analogues pass through the tworollers, the liquid such as the water can be separated out in one stepor can be gradually separated out in multiple steps through thecooperation of the two rollers and the cooperation of the rollers andthe corresponding guiding belts. In this process, the fibers are alwaysin a squeezed state when entering between the two guiding belts, thatis, the separation of the liquid such as the water is not only limitedto the contact position of the two rollers, but also enlarged to betweendifferent rollers and different guiding belts, so that the backabsorption of the liquid such as the water caused by the reduction ofthe pressure can be avoided.

Embodiment 9

The present embodiment has the same setup and working principle withthat of embodiment 1, and differs in that: a least one of the tworollers is connected with a pressurizing mechanism so as to increase thepressure between the two rollers.

Preferably, the pressurizing mechanism adopts an air cylinder (as shownin FIG. 10; the air cylinder (not shown in the figure) is cooperatedwith a big arm 16; the big arm 16 is installed between the air cylinderand the corresponding first roller 1; the air cylinder drives the bigarm 16 to rise and fall to drive the first roller 1 to move up and down,so that the space between the two rollers is changed, that is, thepressure applied to the fibers, the fiber webs or the analogues betweenthe two rollers is changed), an electromagnetic way, a mechanical way ora similar way to lift the corresponding rollers so as to change thepressure between the two rollers.

In each of the above solutions, a water tank 8 can also be arrangedbelow the guiding belt II 4 and used to receive the water squeezed fromthe fibers or the fiber webs. More preferably, the water tank 8 islocated in the loop of the guiding belt II 4. With the water tank 8, theenvironmental pollution caused by the splash of the squeezed water andthe secondary pollution of the fibers, fiber webs or analogues can beavoided. When the water tank 8 is arranged in the loop of the guidingbelt II 4, it is considered that the guiding belt II 4 may move from theoriginal squeezed position to be below the original squeezed positionalong with the rotation of the second driving rollers 6, the squeezedand falling liquid such as the water drops onto the guiding belt II 4and may be carried to the squeezed position again. In order to avoid thesecondary dehydration caused by the carrying, the water tank is arrangedin the loop of the guiding belt to prevent the water from dropping ontothe guiding belt II 4 below the squeezed position, thereby improving thedehydration rate in the entire operation process.

In each of the above solutions, the guiding belt I 3 and/or the guidingbelt II 4 is only used for conveying, and the guiding belt I 3 and/orthe guiding belt II 4 may also be provided with a drain mechanism formedby meshes, leakage holes, a water conveying channel or a moistureabsorption belt.

When the drain mechanism is arranged thereon, the overflow ofthe liquid such as the water from the squeezed fibers or fiber webs canbe facilitated, thereby improving the separation efficiency of theliquid such as the water from the fibers or the fiber webs. According tothe use requirement, the guiding belt I 3 and/or the guiding belt II 4may also select a second solution: the guiding belt I 3 and/or theguiding belt II 4 selects a felt structure, a felt-like structure, aTeflon mesh or a steel wire mesh, so that the mangling effect can beimproved under an extremely small acting force.

In each of the above solutions, the first roller 1 and the second roller2 are arranged vertically in a corresponding manner or in a staggeringmanner. The first roller 1 and the second roller 2 are main parts forsqueezing the fibers, the fiber webs or analogues between the guidingbelt and the mesh belt. When the first roller 1 and the second roller 2are arranged vertically in a corresponding manner as shown in FIG.2-FIG. 7, and when the fibers, the fiber webs or the analogues passthrough the first roller 1 and the second roller 2, the upper surfaceand lower surface thereof are squeezed by the first roller 1 and thesecond roller 2 respectively, and the liquid such as the water israpidly separated from the upper surface and lower surface. When thefirst roller 1 and the second roller 2 are arranged vertically in astaggering manner, the fibers, the fiber webs or the analogues passthrough the first roller 1/the second roller 2 first to be primarilysqueezed between the first roller 1/the second roller 2 and the guidingbelt II 4/the guiding belt I 3, and the liquid such as the water issqueezed out from the fibers, the fiber webs or the analogues, and thenthe fibers, the fiber webs or the analogues continuously pass throughthe second roller 2/the first roller 1 to be secondarily squeezedbetween the second roller 2/the first roller 1 and the guiding belt I3/the guiding belt II 4, and the liquid such as the water is squeezedout from the fibers, the fiber webs or the analogues. In this way, byvirtue of one-time or multi-time squeezing, the liquid such as the wateris gradually separated from the fibers, the fiber webs or the analogues.

The present application is applied to the separation of the liquid suchas water from the fibers, the fiber webs or the analogues. The guidingbelt I 3 is driven by the first driving rollers 5 to rotate; the guidingbelt II 4 is driven by the second driving rollers 6 to rotate; and thefibers, and the fiber webs or the analogues are clamped by the guidingbelt I 3 and the guiding belt II 4 to move forwards under the relativemotion of the two. When the fibers, the fiber webs or the analogues passthrough the first roller 1 and the second roller 2, the liquid such asthe water can be separated in one step or gradually separated inmultiple steps through the cooperation of the first roller 1 and thesecond roller 2 and the cooperation of the first roller 1 and theguiding belt II 4 or the second roller 2 and the guiding belt I 3. Inthis process, the fibers are always in a squeezed state when enteringbetween the guiding belt I 3 and the guiding belt II 4, that is, theseparation of the liquid such as the water is not only limited to thecontact position of the first roller 1 and the second roller 2, but alsoenlarged to between the first roller 1 and the guiding belt II 4 andbetween the second roller 2 and the guiding belt I 3, so that the backabsorption of the liquid such as the water caused by the reduction ofthe pressure can be avoided.
